However, significant problems exist in the relationship between the father and [A], who partly identifies herself with her mother and whose attitude to the father is dictated by [the mother]. Therefore, transferring her to the care of the father may be difficult.
Nevertheless, the existing disturbances in the behaviour of [A] show that the father will better guarantee a proper functional development in future."

42.  On 4 April 2001 the Norwegian Central Authority passed to the Polish Central Authority the applicant's concerns that M.C., who had already hidden the children in the past, might hide them again and asked whether it was possible to take any measures to prevent this and in particular to bring forward the date of enforcement of the court order.
43.  On 9 April 2001 the Polish Central Authority replied in the following terms:
“I would like to inform you that there is no possibility [of executing] the Court decision in another way. It is true that the Court of Justice is allowed to [take preventive] measures but the execution of the measures will be held on the same bases as the [substantive] decision. Mr. N (...)'s anxieties have been transmitted to the proper court.
The [execution of the decision] may not take place before the established date.”

It also advised the Norwegian authorities about new legislation which since 27 September 2001 had made a guardian (kurator sądowy) responsible for the enforcement of court decisions allowing applications for the return of children.

She was under police supervision and was not allowed to leave Poland.
62.  On 28 February 2003 the Białystok District Prosecutor informed the Warsaw District Court that the prosecution service had lodged with the Białystok District Court a bill of indictment against M.C.
